// The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number.
// For example, if using Chilkat v9.5.0.48, then include as shown here:
include("chilkat_9_5_0.php");

$ssh = new CkSsh();

// Connect to an SSH server:
$success = $ssh->Connect('192.168.1.209',22);
if ($success != true) {
    print $ssh->lastErrorText() . "\n";
    exit;
}

// Is the last known state "connected"?
$connected = $ssh->get_IsConnected();
if ($connected == true) {
    // Verify for sure by sending an ignore message.
    $connected = $ssh->SendIgnore();
}

print 'connected = ' . $connected . "\n";
